The parcels, which are adjacent to the parking lot, are owned by Herbert E. Field and Thomas F. Field. A half-acre plot zoned for commercial use has a selling price of $1.1. million and a two-acre portion of a slightly larger lot has a price tag of $1.8 million.

As the two-acre parcel includes farmland, only 30 percent of it may be used for parking; the remainder will be preserved. Accordingly, the town would pay for 30 percent of its cost from capital funds and use community preservation fund money for the remaining 70 percent.

While the town has long eyed the Bistrian land for preservation, years of efforts to hammer out a deal have been unsuccessful.
